A professor, tutor, martial artist,
and archaeologist, Seta plays many roles in the series. He was once Naru's
tutor, and she used to have a crush on him, he is currently a professor,
but is often traveling around the world finding excavation sites. He's
well built and tolerant, but always crashes his van and bleeds like
crazy.

Sara
MacDougal

Sara was adopted by Seta because
she dislikes her American parents. She makes friends with Shinobu and Su
because she is a child who stays at Hinata Inn when her father is out on
expeditions.

Urashima
Haruka

Keitaro's aunt, Haruka seems to be
the head of the Inn. She speaks monotonously, and always carries a
┐cigarette? in her mouth all the time (she never lights it up...if it is
a cigarette).

Urashima
Kanako

Keitaro's younger sister, not
blood-related, and also one who Keitaro made a promise too. Evil, evil,
evil, is what most people would think. However she does have her reasons,
but she just doesn't understand true love and can't accept the fact that
Keitaro has a relationship with Naru. She appears only in the Love Hina
Again OVAs.

Amalla Su

Su's older sister. She hints some
mysterious happenings in Love Hina, but they are all side stories that are
supposed to make Su appear as a more dark and mystical character. Amalla
has a pet white crocodile, probably for protection, and blows a flute to
chant and control her crocodile.

Mei Narusegawa

Mei, Naru's younger sister (not
blood related- Naru's mother married Mei's father), appears in the later
episodes to take Naru back home, right at a critical moment when Naru has
to take the exam for Toudai (Tokyo U). She has deep respect for her
family, and even wants Keitaro to hook up with Mutsumi in order to get
Naru to come back home. Her hair style reminds me of Asuka's =).

Shirai
and Haitani

Keitaro's friends, they never seem
to get anything. You can just call them losers, and they are often seen
trying to get girls but get rejected immediately.

Sakata
Kentaro

Rich and popular, this guy is also
a STALKER. He has literally spied on Naru ever since they met in the
freshman year. He claims to have won her love, but things don't go as he
planned, since Keitaro is whom Naru sets her eyes on. He ends up working
for Haruka later.

Tama

Tama was given to Naru as a present
from Mitsumi. She is capable of speaking and flying (not something an
average turtle can do), but does so rarely. Su always threatens to eat
her, and makes mecha-tamas replicating Tama. In one episode, Tama would
follow Motoko around, which would always give her a scare.

Grandma Hina

Even though the series is named
"Love Hina", Hina rarely appears. In fact she only appears as a
significant character in episodes 1 and 23, in other episodes, she doesn't
make enough of an appearance to be significant. Hina is Keitaro's
grandmother, and judging by her insignificance, they don't seem to have a
close relationship.
